Fourth Suspect Convicted in ’07 Cisse Murder

Demetrius Warren, 21, the fourth of five suspects involved in the 2007 murder of graduate student Amadou Cisse, was convicted of armed robbery and aggravated discharge of a firearm.

Demetrius Warren, 21, the fourth of five suspects involved in the 2007 murder of graduate student Amadou Cisse, was convicted of armed robbery and aggravated discharge of a firearm. Sentencing is pending until October 4th, but State Attorney Mark Shlifka expects that Warren’s attorney will seek a continuance to delay the decision.

Warren could receive up to 80 years in prison for shooting Cisse in the chest four years ago. Benjamin Williams, who was also convicted in the Cisse murder, has already been sentenced to 41 years in prison—35 years for the murder and an additional six years for armed robbery charges.

Last November, Jamal Bracey received a thirty-five–year sentence after pleading guilty to his role in the murder. Another defendant, Eric Walker, the driver of the vehicle used in the crime spree, agreed to testify against Warren in exchange for 20 years in prison. The fifth and final suspect involved in the murder has not been to trial, and Shilfka said he believes the person was merely a passenger and unaware of the crimes the other four were committing.

Cisse was a 29-year-old graduate chemistry student from Senegal. He died from a gun shot wound to the chest in November of 2007, near the corner of East 61st street and South Ellis Avenue. He had already defended his dissertation and was less than a month away from receiving his Ph.D. Cisse was awarded the degree posthumously, and since the year of his murder, violent crime in the Hyde Park, Kenwood, and Woodlawn neighborhoods has decreased dramatically.
